Hi. You are using language not allowed in probuilder.
To draw an indicator you have to write it in a last line starting with RETURN.

// High Jump Indicator
// Calculates the percentage distances from the high price to the 17, 50, and 200 day moving averages.

period17 = 17
period50 = 50
period200 = 200

// Calculate the moving averages
MA17 = Average[period17](Close)
MA50 = Average[period50](Close)
MA200 = Average[period200](Close)

// Calculate the percentage distance from the high price to each moving average
dist17 = (High - MA17) / MA17 * 100
dist50 = (High - MA50) / MA50 * 100
dist200 = (High - MA200) / MA200 * 100

// High Jump Indicator is the sum of the distances
HighJump = dist17 + dist50 + dist200

// Plot the High Jump Indicator (using Plot1)
//Plot1(HighJump, "High Jump", color.red)

// Optionally, you can add a threshold line to indicate when the stock might be over-extended
threshold = 10 // Example threshold for caution flag
//Plot2(threshold, "Threshold", color.green)
return HighJump as "high Jump" coloured("red"), threshold as "Threshold" coloured("green")
